7 '0 all :whom it m (13 concern- Be it known that I, EDWIN E. Serum-of 'Pittsburglnin the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Punching and Shearing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to apparatus used in the manufacture of metal car wheels and similar Cylindrical articles, and more particularly relates to apparatus for punching the axial eye in the hub of such wheels and for removing peripheral fins formed in the forging operation from the forged wheels after the completion of the forging operation.-

Oneobject of the invention is to provide improved apparatus for removing the fins from the periphery of wheels and other cylindrical forged metal articles by shear- Another object of the invention is to provide wheel punching mechanism having novel means whereby the length of the wheel hubs is reduced and fined and the hub length is equalized and made uniform on successive wheels. I p I Another object of the invention is to provide improved means for making or completing the axial opening or axial eye extending through the. hub portion of such wheels and, when the wheels are forged upon a pin, for removing the pins from the hubs of the wheels.

A further object of the invention is to provide improved mcans'for supporting the wheels in position (hiring the punching and shearing operations and for successively bringing the wheels into range of the shear and punch in ca rr ving out the shearing and forging operations. v

Referring to the drawings. Figure 1 is a plan showing shearing and punching apparatus constructed and arranged in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional side elevation on the irregular line III-III of Fig. 1. Fig. 4 is a sectional plan on the line IVIV of Fig. 3 showing the wheel carrier and carrier. supporting mechanism. Fig. 5 is a detail end elevation of the shearing mechanism formingpart of this invention. Fig. (5 is a sectional side elevation of the same on the line VIVI of Fig. .5. Fig. is a plan and Fig. 8 is a side elevation showing in detail the mechanism used for rotating the wheel carrier. Fig. 9 is aside elevation partly'iu section showing a portion of the wheel punching mechanism havmg wheel'strippiug mechanism which may be employed, and the means used in connection with the stripping mechanism for reducin the hub portion of successive wheels to uniform length, the punching ram and pin being shown relative to the wheel in position at the beginning of the wheel punch-. ing operation. F ig. 10 is a sectional view similar to that shown in Fig. 9, showing the punching pin and-ram in position relative to the wheel at the completion of the punching and the hub sizing operations. Fig. 11 is a sectional plan. on the line. XI-XI of Fig. 10, showing a modification in the securing mechanism by which the punching pins are held in position in the end of the ram or plunger forming part of the punching mechanism.

In the drawings, 2 designates a shear having rotary shear knives 3. 3, removably mounted upon the parallel shafts 4. 4". The shear *2- 18 mounted upon an adjustable sup- .port 5 to bring the axes of the shafts 4 and 4* at an angle to the horizontal. The shear 2 and inclined support 5 are movably mounted on the base (3. so as to permit of the shear knives being adjusted horizontally toward and away from the 'wheel carrier 26 -by means of the threaded screw 7 which operates in the nut 8. this nut being mounted in a recess in the sliding support 5. and securely holding the shear and shear support in its adjusted positions.. The bottom shear knife 3 through its shaft 4 is positively rotated by means of the spur gear 9. the'teeth of which are in mesh with the teeth of the spur pinion 10 on the. counter-shaft 11. r The counter-shaft 11 is connected by slow-down gearing with the armature shaft of the motor 12. also mounted on the inclined adjustable shear support Located adjacent to and on one side of the shear 2 is a lluid pressure punch having a. base 13 on which an anvil block 14 is mounted. .\bo've the anvil block 14 is a fluid pressure cylinder 15 which is rigidly secured to the base 13 by means of tie-bolts H The cylinder 15 is provided with a double acting plunger or ram l7 and a head 18 issocured-to the cylinder by means of the clamping rings 19 and ring bolts 20. Fluid pressure is led into and out of the opposite ends of the cylinder 15 through the pipes 21 and 22.

The bottom anvil block 14 is provided with a vertically extending recess 23 which communicates with a transverse opening 24 extending through one side of the anvil block and one end of a chute 25 is located in the mouth of the opening 24 and is arranged to receive and convey punchmgs and, where the'wheels are roller forged upon a pin, the pins away from the recess in the anvil block.

Rotatably mounted upon. one of the tie bolts 16 is a carrier 26' having openings or recesses 27 therein, in each of which a wheel support 28 is mounted so as to be vertically movable. As shown, the supports 28 are provided with central openings 28 in which a pin is inserted .to hold the wheels in position while being rotated. each about its own axis, during the shearing operation by which fins are removed from the periphery of the wheels. As shown in the drawings,

the pins A are inserted tightly in place onthe wheel during the forging operation and are removed with the wheel from the forg-' ing apparatus, in this way providing a convenient means for centering and holding the wheels in position on the wheel support 28 while being sheared. The support 28 as shown is provided on its bottom surface with three recesses 29 registering with similar recesses 30 in the top surface of the carrier 26, and in each of the recesses a helical coil spring 31 is placed for a purpose described later. i i

The carrier 26 is provided with bushings 32 and 33 which form hearings on the tie bolt 16 upon which the carrier is rotatably mounted, the lowermost bushing 33 having a flange portion 33* forming a wearing ring which is adapted to take the end. thrust of the carrier.

Keyed or otherwise secured to the lower end of the carrier 26 so as to rotate with the carrier, is a ring 34. -As shown in the drawings, three equally spaced projecting portions are provided in one face of the ring 34 which form clutch jaws. Rotatably mounted on the lower end. of the carrier 26 is a similarly constructed ring 36 with similar notches in its lower surface having projecting portions 36, which form aws engaging with the jaws 35 in the ring The projections on the engaging faces of the rings 34 and 35 inthis way cooperate to form a jaw clutch. The ring 36 is provided with a peripheral groove in which a rope or other flexible member 37 is placed. The ends of the flexible member are connected by the-turn-buckles or swivels 38 with the ends of the piston rods 39 in the pistons 40 which are mounted in the single acting fluid pressure cylinders 41 and 42, the cylinders 41 and 42 being arranged to rotate the carrier through the jaw clutch formed by the rings 34, 35, and connecting mechanism. The bottom surface of the carrier 26 is provided with lugs 43 and 44, one face of which is arranged to engage with the forward end 45 of the tilting dog 46. The dog is pivoted by the pin 47 to suitable lugs on the side of the anvil block 14 and is connected by means of the rod 48 to the in the cylinder 42, so as to be tilted thereby.

As the wheels placed upon the supports 28 vary in diameter and in size of the opening or hole to be punched in the hub, sizing rings 49 are rcmovably mounted on theupper face of the supports 28, the inner diameters of these rings being .made to suit the size of the particular punch cooperating therewith to form holes or openings of the required diameter through the hub or the wheels.

Removably secured on the lower end of the plunger 0r ram 17 is a punching pin 49, which in the construction shown in Fig. 3, is detachably held in place by means of the flange-5O and flange bolts 51. The lower face of the flange 50 also acts as an anvil face which contacts with the upper faces of and reduces the length of the wheel hubs to a uniform size.

In the modified construction shown in Figs. 9 and 10, the upper end of the punching pin 49 is provided with a peripheral recess or groove and the bottom end of the plunger 17 is provided with a transverse groove or recess, T-shaped in cross section, in which locking plates 52 are secured. The plates 52 are provided with a curved inner edge which enters and engages with the peripheral groove in the ends of the pins 49, these plates being moved into and held in position by means of the adjusting screws 52.

As the friction between the punching pin and the walls defining the opening punched in the hub of the wheel will at times be sufficient to lift the wheels from the supports 28, it is desirable to provide means for preventing such lifting movement. In Figs. 9 and 10. a stripping mechanism is shown which is arranged to engage with and strip the wheels from the pins 49 when the ram 17 is retracted after the punching operation to withdraw the pin from the hole in the hub ofthe wheel. As shown in the drawings, a stripping plate 53 is rigidly secured to the stripper support 54, the stripper plate 53 being cushioned by means ofnthe springs 55, the suppcrt54 being held in position by the bolts 56 which have one end secured to the lower end of the fluid pressure cylinder 15.

In the operation of my improved apparatus, the wheels are successively moved into piston rod 39 engagement with the shear knives and then into position on the anvil block of the punching mechanism. the wheels being placed upon and removed from the wheel supports on the carrier when the supports are in the position indicated by A in Fig. 1. After a. wheel has been placed in position on one of the supports 28 on the carrier 26, the carrier is moved to bring the wheel from the position shown at A, (Fig. 1) into that shown with relation to K the shear. The wheel is then rotated about its own axis on the carrier by contact with the rotating shear knives. the bottom knife 3 of the shear being positively driven by the motor 12 connected through slow-down gearing to the shearing mechanism. After the fin has been sheared from the periphery of the wheel, the fluid pressure cylinders 41 and 42 are actuated to rotate the clutch 36 through a part of a IcVOllltiOIl which in the apparatus shown is one-third of a revolution. This movement of the clutch moves the carrier 26 in a counter-clockwise direction to bring the wheel just sheared into position above the anvil block 14 of the punch in readiness to be punched. The movement of the carrier 26 also brings another Wheel from the position shown at A in Fig. 1 into position in front of the shears to have its fin removed by the shears, during the time the wheel then above the anvil block is being punched and while another wheel is being placed upon the third support on the carrier 26.. The shear knives are then again caused to operate to remove the fin from the periphery of the wheel and at the same timethe plunger 17 is caused to bring the punching pin 49 into engagement with the hub of the wheel beneath this plunger. When the punching pin engages with the upper surface of theQwheel the supporting springs 29 are compressed so that the lower surface of the wheel support 28 is brought into engagement with the top surface of the anvil block 14 to provide the necessary resistance to the punching operation and to remove the strain caused by punching from the carrier 26 to the anvil block. After the punching pin 49 or 49 has completed the eye or axial opening in the hub of the wheel and, when the wheel has been formed upon a pin, the pin has been forced out of the wheel hub, the downward movement of the plunger 17 is continued until the flange 50 forming its lower face or, with the apparatus shown in Figs. 10 and 11. the lower face 53 of the stripper plate 53. is brought into engagement with the hub, and the hub is reduced to a definite length. in this way preventing variations in the hub length of the successive wheels. The lunger 17 is then retracted in the, cylin er 15 to remove the unching pin from the punched Wheel and in the same interval of time the punching operation is being carried out, the shear has also been iictuated to remove the fin from another wheel preparatory to its being punched. The fluid pressure cylinders 41, -12, are then caused to again move the clutch member 36 through the flexible connection 37, and once more rotate the carrier through part of a revolution, this movement of the carrier moving the wheel just punched from beneath the punch into the position A shown in Fig. 1 in readiness to be removed from the carrier. The same movement of the carrier 26 brings the Wheel just sheared into position beneath the punch in readiness for the punching operation.

While the shearing and punching opera tions are bein performed, the sheared and punched whee s are removed from the carrier and a new wheel placed in position on the carrier. It will be seen that every time the carrier 26 is moved one wheel is movcd into position to be sheared,4h=e==-vhcel just sheared is shifted into position to be punched, and the last punched wheel is removed from the punch, and that while the shearing and punching operations are being performed, a sufficient interval of time elapses for the removal of the sheared and punched wheel and the placing of an unshcared and unpunched wheel in position on its sup ort upon the carrier.

During t e punching and shearing operations. it is desirable that the support be held against rotative movement pifihe supporting tie bolt lfi and for this purpose the stops 43 and the lugs 44 are provided on the undcr surface of the carrier 36. tilting locking h1g4?) having a counterwcighted portion it) is pivoted to the ears or lugs 47 on the anvil block 11 so that the horizg nlally extending portion 4.3 of this locking dog engages wilh the stop 43 on the lugs 44 and securely holds the carrier 26 against rolative movement in one direction while the dog is in the position shown in Fig. 3, movement in the op osite direction being prevented by the cylim er 41 and its connecting mechanism. \Vhen fluid pressure is admitted to the cylinder -12 to move the piston rodsiiS) in the cylinders ll and 42, the flexible connection 37 moves thojaw member 36 in a clock-wise direction. This jaw member 36 being rotatably mounted on the carrier 26. its inclined jaw surfaces will cause it to lift and slip on the lower jaw member 33 of the clutch so as to rotate in a clock-wise direction without moving the carrier 9.43. \Vhen the forward end of the piston rod 39 nears the end of its stroke. the clevis on the cnd of this piston rod engages with the hooked end of the rod 49 and tilts the forward end of the locking log 45 until it out of engagement with the stop 43 on the carrienlfi. \Vhen the jaw member 36 is rotated in the opposite or in a counter-clockwise direction to move the carrier 26 the connection 48 holds the dog in depressed positionlong enough for the stop and lug to pass over this dog and as the carrier is again brought into position the next stop 43 again engages with the dog, which is released when the jaw member 36 is reciprocated in moving the -arrier another step forward.

In some cases it will be found desirable to hold the. wheels against vertical nnn'ement while the plunger 17 is being retracted, and in Figs. 9 and 1a is shown one form of st ripping apparatus which is adapted for use with the punch shown. In this stripping apparatus a stripper 53 is yieldingly connected to the bottom end of the cylinder 15 by means of separator bolts 56 and springs 55. \Vhcn the plunger 17 is retramtcd the top face of the hub of the wheel engages with the stripperplate 53 and holds it against further lifting movement while the pin 49 is being withdrawn from the hole or axial eye formed in the wheel by the punching operation.

Vhen the punching operation is completed, the springs 31 lift the support; 28 out of engagement with the anvil block 14 so as to clear the top face of the anvil block sufficiently to permit of the easy rotation of the support 28 and carrier 26 in its forward movement.

The advantages of my invention will he apparent to those skilled in the art. By the use of my improved apparatus the fins are rapidly and easily removed from the periphery of the wheels. The wheels are punched in a simple and effective manner and the wheels after being placed in position on the. carrier, in a series of successive steps, are carried to the shear. from the shear to the punch. and from the punch to the point at which the sheared and punched wheels are removed from the carrier. The punch ing and shearing operations are carried out simultaneously and during the punching and shearing operations a sufiicieut interval of time is provided to permit of the sheared and punched wheels being removed from the carrier and an unpunchcd. unsheared wheel being placed in position upon its support on the carrier in readiness to be sheared and punched. In this way a saving of time is effected and the number of shearing and punching machines necessary to handle a given quantity of wheels is lessened. The apparatus is simple and is easily kept in repair.

Modifications in the construction and an rangement of the parts may be made without departing from my invention. Instead of having three wheel supports upon the carrier a greater or le ser number may be employed. The mechanism for operating the carrier may be changed, shearing and punching mechanism other than that shown may be used and other changes made within the scope of the appended claims.
